Benefits of technology

The Inventors have found, surprisingly, that the use of N-(3-chloroallyl)hexaminium chloride, also called 1-(3-chloroallyl)-3,5,7-triazo-1-azoniamadamantane chloride (also known by the CTFA name: Quaternium-15), even in a very little amount, gives particularly effective protection against microorganisms (e.g., bacteria, yeasts and moulds) and produces a composition that is suitable for impregnation onto a support.

Problems solved by technology

However, the bacteriological protection of a wipe poses specific problems by the fact that the contact surface with air is much greater than the contact surface of a product which is in a jar or in a flask, that increases the risk of contamination and, thus, needs a better bacteriological protection.

example 1

Makeup-removing Milk (O / W Emulsion)

Procedure: phases A and B are separately heated at 75 / 80.degree. C. Phase A is added to phase B with stirring, and this stirring is then maintained for 5 minutes. Phases C and D are then added, followed by cooling with stirring. Phase E is added at 30.degree. C. The mixture is cooled to room temperature (about 25.degree. C.) and a milk is obtained.

The wipes impregnated with this makeup-removing milk allow makeup to be removed from the face and the eyes without irritation, while at the same time having very good antibacterial conservation.

example 2

Makeup-removing Milk (PIT Emulsion)

Procedure: Phase A is prepared by the known means for emulsifying according to the phase inversion temperature process (PIT technique). After cooling to room temperature, phase B is introduced with gentle non-shear stirring. According to one preferred preparation method, the mixture of cetearyl isononanoate, ceteareth-20, cetearyl alcohol, glyceryl stearate, glycerol, ceteareth-12 and cetyl palmitate, sold under the name Emulgade CM by the company Cognis, is used to prepare phase A. After introducing the fragrance into this mixture at room temperature, phase B is introduced just before impregnation of the supports.

example 3

Makeup-removing Lotion (Aqueous Lotion)

Procedure: the demineralized water is heated to 80.degree. C., followed by successive addition, with stirring, of the disodium cocoamphodiacetate, the hexylene glycol, the methylparaben and then the disodium EDTA. This mixture is cooled to 40.degree. C. with stirring. At this temperature, the Quaternium-15 is added, followed by the triethanolamine. The mixture is cooled to 25.degree. C. and the lotion is obtained.

A 70 / 30 viscose / polyester nonwoven, with a weight per unit area of 65 g / m.sup.2, is impregnated with 325% by weight of composition relative to the weight of nonwoven, with the compositions of Examples 1 to 3, and is then cut into the form of rectangular wipes 150 cm.times.200 cm in size.

A polyurethane foam can also be impregnated, for example to 100% by weight of composition relative to the weight of foam, with the compositions of Examples 1 to 3. It will advantageously be in the form of a round compress 70 mm in diameter and 1.5 mm th...

Abstract

The invention relates to an article containing (A) a water-insoluble substrate and (B) containing an aqueous phase and N-(3-chloroallyl)hexaminium chloride. According to one preferred embodiment of the invention, the composition also contains at least one C1-C4 alkyl para hydroxybenzoate and / or at least one ethylenediamine-tetraacetic acid salt. The article may especially constitute a wipe for cleansing and / or removing makeup from the facial and / or body skin, and also for removing makeup from the eyes. The wipe may be in the form of a moist or dry wipe.

Description

1. Field of the InventionThe invention relates to an article, preferably a wipe, comprising (A) a water-insoluble substrate, and (B) a composition added to, impregnated onto, in contact with, etc. the substrate comprising an aqueous phase and N-(3-chloroallyl)hexaminium chloride (Quatemium-15). The invention also includes the uses of this article in cosmetics or dermatology, in particular for cleansing and / or removing makeup from the skin, more especially of the face, and of the eyes.2. Background of the InventionFor cleansing or removing makeup from the skin, it is known practice to use compositions of the lotion or milk type which are applied to a cotton-wool support at the time of use, and applied to the face.It is also known practice to use moist wipes which contain an impregnation composition for cleansing or removing makeup from the skin, thus avoiding the handling and transportation of bottles containing lotions or milks. These wipes generally consist of a substrate made of a...
